Computer-related eye strain
Read & Share
Patients often mention that after prolonged computer use, their eyes feel tired and they may have a headache. This is often due to the proximity of the screen or dryness of the eyes. During tasks that require concentration, we tend to blink half as often as normal, allowing our eyes to dry out. Also, when working on the computer, we tend to focus at near, which can cause slight headaches.
To avoid computer-related eye strain;
1) use a lubricating drop (not visine or clear eyes),
2) take frequent breaks,
3) every 20 minutes, look at a target that is far away.
